Measuring pad arrangement for a logging sonde
This patent describes a logging sonde for use in a borehole traversing an earth formation. The logging sonde comprising: an elongated sonde body; a plurality of measuring means for measuring a characteristic of the earth formation. Each of the measuring means comprising: a central element; a first measuring flap hingably connected to the central element; a second measuring flap hingable connected to the central element. The measuring flaps being disposed on either side of the central element, the first measuring flap staggered relative to the second measuring flap along the longitudinal direction of the sonde body; means operatively connected between the sonde body and the first and second measuring flaps for applying a resilient force to each of the measuring flaps, thereby tending to move the flaps away from the sonde body; and means connected between the sonde body and each of the measuring means for translocating the measuring means away from and back to the sonde body.
